Application filed September 13, 1906- Serial No. 334,476.

To all whom it may concern:

Beit known that I, le RANK BowEN, a citizen of the United States, residing at Purdy, in' the county of Barry and State of Missouri, have invented a new and useful Ealing-Press,l of which the following is a specification.

This invention relates to apparatus for baling hay, straw, and other material, and has for one of its objects to provide a mechanism of simple character inwhic'h a baling wire or a number of baling wires, may be fed across the baling chamber at a point to the rear of the compression face of the plunger, and the opposite ends of the wire twisted or otherwise united, the plunger being provided with a passage to permit the escape of the wires' after the twisting operation.

A further obj ect of the invention is to provide a press in which the plunger has passages for the bale wires, to `permit the wires to pass from side to side of the press, and is provided at the front end, or compression face with openings, which will permit the passage of the wires during, or alter the twisting operation.

A still further yobject of the invention is to provide a \press having a plunger provided'with wire passages, the compression face ofthe plunger having pivoted `doors which will open to permit the outward passage of thelbale wires, andhthen close to form a smooth solid face for engagement with the material to be compressed.

A still further object of the invention is to provide a novel form of twisting mechanism including revoluble holding devices,y which receive the-'loops of wire fed across the baling chamber, and move said wires into of cutting mechanisms, which operate to sever the wire after each twisting operation.

.A still further obj ect of the invention is to construct a press having a twisting mechanism, that is operated directly from the power head, so that a twisting operationwill occur after a predetermined/number of reciprocations of the compression plunger.

With these and other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of construction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that varions changes in the form, proportions, size and minor the invention.

from the spirit or sacrificing any of the advantagesof In the, accompanying drawingsz-Figure 1 is a'plan view of a baling press constructed in accordance with the same on theline 2-'2 of Fig. 1. Fig. 3 is a vertical section, illustrating the twisting mechanism, the' sec.

tion being on the plane indicated by the line 3--3 of Fig. 2.. Fig. 4 is a sectional plan view` of the press and twisting mechanism on the line 4 4 of Fig. 2. Fig. `5 is a detail perspectiveview of one of the twisters detached. Fig. 6 is a sectional'view on an enlarged scale v through a portion of the plunger. Figs. 7 and 8 are diagrams. illustrating the operation of the machine. Similar numerals of referenceare employed to indicate corresponding partsvthroughout the several figures of the drawings. I I v The press boit 10 is provided with upper andlower sets of rolls to facilitate the bale forming operation, and said press box is connected bya suitable beam 11 to the frame l2 of the power head, and this frame has a vertically disposed shaft 13, to the upper end of which is secured a disk 14, and from the latter projects .a sweep 15,*where the device is to be operated by ani.-

mal power. To the lower portion of the shaft 13 is sedisposed shaft 21, through which movement is imparted from the power head to the bale wire twisting devices. l i

The rear end oi the compression plunger 24 is provided with a guide bar 25 extending through a suitable guiding opening formed in the upper walls 26 of the power head frame, and is further connected by a pitman 28 to a crank disk 29 on theshaft 18, this mechanism serving to impart the necessary reciprocatory movement to the plunger.

The material to be compressed is inserted in the baling chamber at 30, and isoperated upon in the usual :manner by the plunger which forces the material toward the discharge end of the press box.

In order to add to the resistance to the movement of the material as it discharges from the press box, and

thus increase the degree of compression of the bale, a

cables or chains 34 which pass around winding drums 35 on a shaft 36 journaled at the top ofthe press frame.

This shaft is' provided with a handled crank 37 which may be turned in order to alter the angle of the chute 33, and'thus increase or decrease the resistance offered tothe discharge of the baled material, and at the same 1 0 5 i To facilitate the discharging operation, the chute vided with grooved sheaves 39 for the reception of a belt 40 that isguided into Contact with said sheave by idlers 41, the belt passing also around a small sheave 42 on a vertically mounted shaft 43 that constitutes a part of the actuating mechanism of the tier.

The plunger 24 is provided with horizontal slots 50 oi a number equal to the number of bale wires, two in the present instance, and these extend for nearly the whole length oi the plunger and are for the purpose of permitting the passage ol' wire carrying needles 51 by which the bale. wires are fed transversely across the baling chamber, the wires passing through the slots 5t), so that during the twisting operation a portion of the plunger is practically included with the bale, the bale wire escaping through a contracted passagev52 in the face of the plunger. Each of the passages 52 isnor- 1n-ally closed by a pivotally mounted spring held door 53, so that a' practically smooth, solid face is formed for engagement with the material to be compressed. The doors, however, will open to an extent su cient `to permit the passage of the wires during, or immediately after the twisting operation.

The two needles 51 are carried by a vertically disposed bar 56, the upper end of which is secured to a cross head or slide 'block 57 adapted to suitable guiding bars 58 projecting laterally from the top of the press box. The cross head is connected by a link 59 to a crank pin 60 on a mutilated gear 6l that is carried by.

a vertically disposed shaft 62, the shalt being journaled in bearings on the top of the press box. This shaft 62 carries a pinion 63 that is engaged by a mutilated gear.

64 carried by the vertically disposed shaft 43, and at the lower end of the shaft 43 isa beveled gear 65, intermeshing with a bevel pinion. 66 on the obliquely disposed transmission shaft 21. l.

It will be seen that owing to the mutilated gear 64 and the relative `proportions oi the several gears that the power head may be rotated a number oi times, seven or eight for example, to compress enough material to form a bale, and then during the final operatiop the teeth oi the mutilated gear 64 will engage with and Irevolve the pinion 63 and impart a single rotative movement to the shaft 62, and thus effect a single re` ciprocatory movement of-the needle carrying block 57 The baling wire is carried by reels 70, mountedon a vertical spindle 7l at the left hand side oi the press, or that side on which the transmission shaft 21 is disposed, and the wires pass along and under the needlesto the free ends thereof, and thence extend through eyes 72 in the needles. Immediately tothe rear of each eye the needle is recessed, as indicated at 73, so that a portion of the wire is stretchd across the mouth of the recess, and is in a' position to be engaged by one of the wire holders, and retained whilethe needle starts on its rearwardzmvement. [At the right hand side of the press is arranged the frame` of the twisting mechanism, and in the vetical portion/0i the frame are arranged openings 81 for the passage of the two wire needles.

The frame 80 is provided with bearings for a .vertically disposed shaft 82 carrying two disksA 83', one for each-of the needles, and so arranged that their upper faces are immediately below the lower edges o said needles, the latter passing over the disks at each opesation. hearing against the peripheries or" the disks is a wire clamping plate 84 that is pivoted on a pin 85 carried by the frame, the plate having a coneaved surtace to iollow closely the peripheries of the disks. be

ing held in engagement therewith by a spring 86, the stress of which may be adjusted by a suitable screw 87. This presser plate is preferably formed of two members, one ol' which, 88, is pivoted-to the other, and both are yieldab-ly held in engagement with the disks. i

Each disk carries l'our wire engaging fingers 90, that I have pointed end portions projecting above the disk and arranged in such' manner that as the latter is rotated they will pass through the space or recess 73v of the needle and engage the loop of wire stretched across the mouth of said redess, the wire being carried thence into engagement; with the pivoted c lamp 88 and conned between said clamp and the tngerQO. As each of the disks carries four clamping lingers, and each disk receives a ninety degree movement at each operation, it follows that the clamping.v fingers will act in successive order when moving the"'wire into engagement with the clamping member 88 at a point near the entrance end thereof, and then WhenI the second clamping finger engages a wire and moves it to the position o the first, said first clamping finger will carry its wire around into engagement with the heel of-the clamping member 84, as clearly illustrated in Fig. 4, so that two wires may thus be held by the clamping devices and b'oth of them passed over the outer edge oi the clamp 88, the latter being preierably provided with guiding notches for holding said wires in proper position. l

On the upper end of the shaft 82 is arranged a bevel gear- 94, with which` engages a mutilated bevel gear 95 on a shaft 96 held in suitable bearings at the top of the frame. This. shaft is provided with a small bevel pinion 97Y which meshes with the mutilated gear 61 and receives a complete rotative movement therefrom at each operation, and this movement is transmitted through the mutilated gear 95 to the gear 94, the latter receiving a ninety degree movement at each operation. Theframe carries a stationary cutting knife 98 having two notches, provided with cutting edges and arranged 2 for the reception ofthe wires. These notches 99 are in alinemerit with the notches' at the edge of the wire clamp 88. At one side of the stationary knife 98 is guided a movable knife 101 having notches 102 provided with sharpened cutting edges, and the top of the knife 101 is connected by a link 103 to a crank pin 104 carried by the shaft 96, so that at each rotative movement of the shaft the wires lying within said notches will be severed.

The frame 80 is provided with a pair of horizontally disposed spindles or studs 105 arranged adjacent to the openings 81, and on each of these is mounted a rusto con ical twister head 106 provided with a pair of diametrically opposed sets of twisting pins' 107. Each set of pins com lrises two members arranged on lines tangential with respect to the body portion 106, and between the. pins is arranged a guard 108 that extends partly around the twister and prevents accidental displacement of the wire during the twisting operation. The twisting pins are so arranged as to engage with the wire passing through the openings 8l, each twister grasping two Wires, and intertwisting the same. On the base of each l twister is secured-a. -gear 1l() that is connected by an in'- termediate gear 111 to a train of gears 112, all journaled on studs carried vby the frame. The uppermost gear of the train intermeshes with the teeth oi a gear 113 which receives motion from a mutilated gear 114 on the shaft 9G, said gear 114 having teeth for approximately one halt of its periphery and serving at each movement to impart a complete rotative movement to the-gear 113, and this movement isv transmitted to the twister's in order to effect any desired number of rotations of the latter.

Iniheoperationoi the device, the compression of the bale proceeds in the usual manner until at theend of a predetermined number of compression movements of the plunger, the gear 64 engages with the pinion 63 and rotates the latter, thus rotating gear 6l and imparting movement through crank G0 and rodi59 to the needle carrying block 57. The needles are thrust across the baling chamber through the slots 50 of the plungenand the wires carried thereby are presented above the disks 83, At the proper moment one ofthe fingers 90 of each disk will engage the wire and move the same into engagement with the wire clamp 88. `It is to be noted that from a previous operation, the end of a wire has been held in a preceding finger 90, and is moved thereby into engagement with the heel portion of the clamp 84, so that the two wires held vby the two clamping members 90 then extend thronghihe notches of the cutter, and are disposed in the 'path of movement of the twister pins. The twisters are immediately started in to operation, and the wires are twisted together. During this operation their ends are held by the clamps, and the tendency, then-fore, is for the wire which extends across the plunger slot to pass through the opening 52 in the com pression face of the plunger, and this will be accomplished to an extent proportionate to the amount of twist given the wire, but if the twist is not sufficient for the purpose, the rearward movement of the plunger will immediately cause the wire to pass out through the Y 40 `opening. At the completion of'the twisting operation the wires are severed at the operation oi the vertical movable cutter 101, it being noted that one end of the wirelit still held between one of the fingers 90, and the clamp 88. The needles, however, retreat during the twisting operation and carry the wire across the baling chamber and through the plunger, so that as the latter recedes the Wire extending transversely across the baling chamber will pass through the opening 52, and be disposed in a position in advance of the'plunger in readiness to receive therst part of the next bale.
